FIG. 1 is a diagram illustrating a power supply mechanism 110 of amovable container 10 according to an embodiment of the presentdisclosure. The power supply mechanism 110 includes a housing 200embedded in a top surface 120 of the movable container 10. The housing200 includes a recess REC for receiving a to-be-charged device. Thepower supply mechanism 110 further includes a cover 300, a charging coil400, and a control device 500. The cover 300 is partly jointed with therecess REC. The charging coil receives a current and provides electricalpower wirelessly accordingly to perform wireless charging upon theto-be-charged device. The control device 500 is arranged to control thepower supply mechanism 110 and provides electrical power when a supplycondition is fit. In this embodiment, the control device 500 includes abuckle 510 and a switch 520, wherein the buckle 510 is attached to thecover 300, and the switch 520 is embedded in an opening on the housing200 and electrically connected to the charging coil 400. With suchconfigurations, when the cover 300 is closed, the buckle 510 activatesthe switch 520, and the charging coil 400 receives current and providesthe electrical power wirelessly.

Alternatively, the control device 500 may include another switch, e.g.,a button switch 600. The button switch 600 is embedded in the housing200. When a user activates the button switch 600 by pressing, thecharging coil 400 receives current and provides the electrical powerwirelessly. The to-be-charged device may be a wristband, a smart watch,or a smart phone, and such devices are associated with the movablecontainer 10 for controlling the movable container 10. When theto-be-charged device is being charged, such device is placed in therecess REC and receives the electrical power from the charging coil 400.The power supply mechanism 110 may further include a light source 700such as a Light Emitting Diode (LED). The charging coil 400 may provideelectrical power to illuminate the light source 700. In otherembodiments, the light source 700 and the button switch 600 may beintegrated together. In other words, when a user activates the buttonswitch 600, the button switch 600 illuminates.

FIG. 2A and FIG. 2B are diagrams illustrating the charging coil 400according to an embodiment of the present disclosure. In FIG. 2A, thecharging coil 400 is attached to the bottom of the recess REC. In FIG.2B, the charging coil 400 is attached to the bottom surface of the cover300. In the embodiments of FIGS. 2A and 2B, the charging coil 400 mayreceive the current via a wire coming through the housing 200 and thewire is connected to a power supply source (e.g., a detachable battery)external to the recess REC. FIG. 3 is a diagram illustrating the movablecontainer 10 while charging an electronic device according to anembodiment of the present disclosure. The electronic device (e.g., thewristband or the smart watch mentioned above) is placed in the recessREC with the cover 300 being closed and receives the electrical powerprovided by the charging coil 400. The light source 700 illuminates toindicate that the electronic device is being charged. Preferably, atleast a part (i.e., a part or all of it) of the cover 300 may be made ofa transparent material. With such configurations, users can check thecharging status of the electronic device or messages displayed on thescreen through the transparent cover 300.

FIG. 4 is a diagram illustrating an outer shell 100 of the movablecontainer 10. A surface SUR of the outer shell 100 includes a first partP1 and a second part P2. As shown in FIG. 4, a height deviation existsbetween the first part P1 and the second part P2 on the x direction. Inother words, the second part P2 can be seen as a recess of the outershell 100.

FIG. 5 is a diagram illustrating a power supply mechanism 130 of themovable container 10 according to another embodiment of the presentdisclosure. The movable container 10 includes a handle HD having a topHD_T and a rod HD_R. The rod HD_R is embedded in a handle tube TB. Thehandle tube TB is located between the first part P1 and the second partP2 of the surface SUR of the outer shell 10. In this embodiment, thehandle HD is stretchable. When the handle HD is retrieved from stretch,the rod HD_R is fully embedded in the tube TB while the top HD_T isbelow or level with the top surface of the outer shell 100 and above ahandle-top receiving structure S1 of the outer shell 100. The handle-topreceiving structure S1 can be seen as a part of the part P1. As shown inFIG. 5, the handle tube TB preferably equally divides the compartmentsurrounded by the first part P1 and the second part P2, and twosub-compartments SUB1 and SUB 2 are formed adjacent to the tube TB. Thepower supply mechanism 130 includes an inner part INN and an outer partOUT. The inner part INN is attached to the surface SUR of the outershell 100 via an attachment mechanism. In this embodiment, theattachment mechanism includes an adhesive. In other words, the innerpart INN is glued to the outer shell 100 (in particular, to the secondpart P2 of the surface SUR and the handle tube TB), and the power supplymechanism 130 is accordingly embedded in the outer shell 100 of themovable container 10. In other words, the power supply mechanism 130covers the tube TB and the sub-compartments SUB1 and SUB2.

The outer shell 100 and the power supply mechanism 130 are made ofdifferent materials. The power supply mechanism 130 is made by amaterial whose hardness is relatively lower than the material used tomake the outer shell 100. With such configurations, when the movablecontainer 10 is suffered from collision, the power supply mechanism 130mitigates the shock to prevent stuff stored inside the power supplymechanism 130 from being damaged.

FIG. 6 is a front view diagram illustrating the charging coil 800 in theinner part INN of the power supply mechanism 130 according to anembodiment of the present disclosure. As shown in FIG. 6, inside theinner part INN, two storage bags B1 and B2 are sewn on the inner partINN and located in the sub-compartments SUB1 and SUB2 respectively forreceiving stuff. At least a part (i.e., a part or all of it) of eachstorage bag is by an elastic band for fixing stuff stored therein toprevent the stored stuff from randomly moving. In this embodiment, acharging coil 800 is sewn in the inner part INN and covered by a fabric,and also attached to the second part P2. The charging coil 800 receiveselectric current from a power supply source (e.g., a detachable battery)to provide electrical power wirelessly. For example, the charging coil800 is behind the bag B2 as shown in FIG. 2. The to-be-charged devicemay be received by the bag B2 and the power supply source (e.g., adetachable battery) is received by the bag B1, and the detachablebattery electrically connects to the charging coil 800 via a wire. Withsuch configurations, the charging coil 800 thus provides the electricalpower to charge the to-be-charged device wirelessly.

However, the charging coil 800 is not limited to be sewn in the innerpart INN and to be attached to the second part P2. FIG. 7 is a diagramillustrating the charging coil 800 in the outer part OUT of the powersupply mechanism 130 according to an embodiment of the presentdisclosure. As shown in FIG. 7, the charging coil 800 is sewn in theouter part OUT and covered by a fabric FBC. For example, the chargingcoil 800 is sewn in a location corresponding to the bag B2. Theto-be-charged device may be received by the bag B2 and the power supplysource (e.g., a detachable battery) is received by the bag B 1, and thedetachable battery electrically connects to the charging coil 800 via awire. With such configurations, the charging coil 800 thus provideselectrical power to charge the to-be-charged device wirelessly. Inaddition, the outer part OUT is attached to the first part P1 of thesurface SUR via a zipper (not shown in figures). However, this shouldnot be a limitation of the present disclosure. In other embodiments, abuckle, a latch or a magnet is adapted for the outer part OUT beingattached to the first part P1.

For example, the power supply mechanism 130 includes a control deviceincluding a buckle (e.g., the buckle 501) and a switch (e.g., the switch502), wherein the buckle 501 is attached to the outer part OUT and theswitch is embedded in the outer shell 100 (e.g., the handle-receivingstructure S1). When the outer part OUT closes up the sub-compartmentsSUB1 and SUB2, the buckle on the outer part OUT activates the switchembedded in the outer shell 100, and the charging coil 800 thus providesthe electrical power. For another example, the power supply mechanism130 includes a control device including a magnet and a switch. Themagnet is embedded in the outer part OUT and the switch is embedded inthe outer shell 100. When the outer part OUT closes up thesub-compartments SUB1 and SUB2, the switch is activated by the magnet,and the charging coil 800 thus provides the electrical power. However,these examples are only for illustrative purpose, it is not a limitationof the present disclosure. In other embodiments, the charging coil 800may be activated to provide the electrical power by other methods.

Refer back to FIG. 5, a button switch 900 is embedded in the outer shell100. When a user activates the button switch 900 by pressing, thecharging coil 800 receives current and provides the electrical powerwirelessly to charge the to-be-charged device which is placed in theinner part INN (in particular, the bag B1 or B2). A light source 1000such as a Light Emitting Diode (LED) may be embedded in the outer shell100. The charging coil 800 may provide the electrical power toilluminate the light source 1000. In other embodiments, the light source1000 and the button switch 900 may be implemented together. In otherwords, when a user activates the button switch 900, the button switch900 illuminates. In addition, the locations of the button switch 900 andthe light source 1000 are not limited by the present disclosure. Inother embodiments, the button switch 900 and the light source 1000 arelocated on the rod HD_R of the handle HD.

FIG. 8 is a diagram illustrating the movable container 10 according toan embodiment of the present disclosure. As shown in FIG. 8, adetachable battery DB is placed in one of bags (e.g., the bag B1) on theinner part INN for providing current. The to-be-charged device such asan electronic device ED is placed in either the other bag (i.e., the bagB2) on the inner part INN or the recess REC. For example, the electronicdevice ED is placed in the bag B2 as shown in FIG. 8. When the outerpart OUT closes up the second part P2, the detachable battery DB cannotbe seen from outside. In other words, the detachable battery is placedin the outer shell without protruding any external corner of the shell.

The movable container 10 includes a power distribution board PDBarranged to transfer current provided by the detachable battery DB tocomponents installed within the movable container 10. In otherembodiments, the power distribution board PDB can not only transfer thecurrent provided by the detachable battery DB, but actively adjust thecurrent provided to the components. In addition, the power distributionboard PDB is embedded in the outer shell 100 and cannot be seen fromoutside. It should be noted that, the location of the power distributionboard PDB is not limited by the present disclosure. The powerdistribution board PDB is electrically connected to the detachablebattery DB via a wire.

The movable container 10 further includes a charge level sensor CLSelectrically connected to the detachable battery DB. The charge levelsensor CLS is arranged to monitor the charge level of the detachablebattery DB and transmit an indicator signal to the power distributionboard PDB. For example, when the charge level of the detachable batteryDB is lower than a first predetermined value, the charge level sensorCLS transmits the indicator signal to inform the power distributionboard PDB, and the power distribution board PDB stops transferring thecurrent to the charging coil 400 or 800 accordingly. In other words, themovable container 10 terminates the wireless charging function when thecharge level of the detachable battery DB is lower than the firstpredetermined value.

It should be noted that, the current is not limited to be transferred tothe charging coil 400 or 800 via the power distribution board PDB. Inother embodiments, the charging coil 400 or 800 is electricallyconnected to the detachable battery DB via a wire without the powerdistribution board PDB.

Referring to FIG. 8 again, the movable container 10 further includesmotor M1 to M4 associated with wheels W1 to W4. The motors M1 to M4 maybe attached to the outer shell 100 by latch, buckle, or magnet. This isnot a limitation of the present disclosure. The power distribution boardPDB transfers the current to motors M1 to M4 so that motors M1 to M4 canprovide a momentum to the movable container 10 by driving wheels W1 toW4. It should be noted that the power distribution board PDB mayactively adjust the current planned to be transferred to each motor. Byreducing the current being transferred to motors associated with innerwheels and increasing the current being transferred to motors associatedwith outer wheels, the movable container 10 is able to make rotationmovement. In this embodiment, when the charge level of the detachablebattery DB is lower than a second predetermined value, the charge levelsensor CLS transmits the indicator signal to inform the powerdistribution board PDB, and the power distribution board PDB stopstransferring the current to the motors M1 to M4 accordingly. In otherwords, the movable container 10 terminates the self-driving functionwhen the charge level of the detachable battery DB is lower than thesecond predetermined value. In this embodiment, the second predeterminedvalue is lower than the first predetermined value. However, this is alimitation of the present disclosure.

Referring to FIG. 8 again, the movable container 10 further includes asensing mechanism SSN. The sensing mechanism SSN is electricallyconnected to the power distribution board PDB, and arranged to sense adistance feature and/or a recognition feature in accordance with themomentum provided by the motors M1 to M4. Specifically, the sensingmechanism PDB receives current from the detachable battery DB via thepower distribution board PDB. In this embodiment, the sensing mechanismSSN locates on a side of the movable container 10 and includes an imagesensor and a proximity sensor. For example, the image sensor is arrangedto sense the distance feature and/or a recognition feature forpeople-following in accordance with the momentum provided by motors M1to M4. The proximity sensor is arranged to avoid the movable container10 colliding any obstacle. With such configurations, the movablecontainer 10 may follow a target in accordance with the distance featureand the recognition feature. In this embodiment, when the charge levelof the detachable battery DB is lower than the second predeterminedvalue, the charge level sensor CLS transmits the indicator signal toinform the power distribution board PDB, and the power distributionboard PDB stops transferring the current to the sensing mechanism SSNaccordingly. In other words, the movable container 10 terminates thesensing function when the charge level of the detachable battery DB islower than the second predetermined value.

It should be noted that, the locations of the sensing mechanism SSN arenot limited to be on the side of the movable container 10. In addition,the current is not limited to be transferred to sensing mechanism SSNvia the power distribution board PDB. In other embodiments, the sensingmechanism SSN is electrically connected to the detachable battery DB viaa wire without the power distribution board PDB.

Referring to FIG. 8 again, the movable container 10 further includes anavigation mechanism NAV. The navigation mechanism NAV is electricallyconnected to the power distribution board PDB, wherein the navigationmechanism NAV is arranged to provide a location information of themovable container 10. In this embodiment, the navigation mechanism NAVis embedded in the outer shell 100. However, the location of thenavigation mechanism NAV is not limited by the present disclosure. Thenavigation mechanism NAV may include a global positioning system (GPS)or an indoor positioning system such like a simultaneous localizationand mapping (SLAM), a visual simultaneous localization and mapping(VSLAM), an indoor positioning system, a Wi-Fi positioning system (WPS)or iBeacon to provide the location information of the movable container10. In this embodiment, when the charge level of the detachable batteryDB is lower than the second predetermined value, the charge level sensorCLS transmits the indicator signal to inform the power distributionboard PDB, and the power distribution board PDB stops transferring thecurrent to the navigation mechanism NAV accordingly. In other words, themovable container 10 terminates the navigation function when the chargelevel of the detachable battery DB is lower than the secondpredetermined value.

It should be noted that, the current is not limited to be transferred tothe navigation mechanism NAV via the power distribution board PDB. Inother embodiments, the navigation mechanism NAV is electricallyconnected to the detachable battery DB via a wire without the powerdistribution board PDB.

Referring to FIG. 8 again, the movable container 10 further includes alock LCK. The lock LCK is electrically connected to the powerdistribution board PDB, wherein the lock LCK is arranged to change alock status of the movable container 10. In this embodiment, when thecharge level of the detachable battery DB is lower than a thirdpredetermined value, the charge level sensor CLS transmits the indicatorsignal to inform the power distribution board PDB, and the powerdistribution board PDB stops transferring the current to other elements(e.g., the sensing mechanism SSN, the charging coil 400 or 800, thenavigation mechanism NAV, or the motors M1 to M4) but only transferringthe current to the lock LCK. In other words, the movable container 10remains the electronic lock function exclusively when the charge levelof the detachable battery DB is lower than the third predeterminedvalue. In this embodiment, the third predetermined value is lower thanor equal to the second predetermined value. However, this is not alimitation of the present disclosure.

It should be noted that, the current is not limited to be transferred tothe lock LCK via the power distribution board PDB. In other embodiments,the lock LCK is electrically connected to the detachable battery DB viaa wire without the power distribution board PDB. In one embodiment,users of the movable container 10 may set up those predetermined valuesor the priority of abovementioned functions receiving current from thedetachable battery DB through an application on a smart phone associatedwith the movable container 10. For example, the user may decide that thesensing mechanism SSN is more important than the navigation mechanismNAV, and set up the sensing mechanism SSN with a higher priority ofreceiving current from the detachable battery DB than that of navigationmechanism NAV via the application on the smart phone. With suchconfigurations, when the charge level of the detachable battery DB isgetting lower, the movable container 10 may terminate the navigationfunction before the sensing mechanism SSN.
